An op amp differential amplifier can be created by combining both a non-inverting voltage amplifier and an inverting voltage amplifier in a single stage. Proper gain matching between the two paths is essential to maximize the common-mode rejection ratio. Differential gain is equal to the gain of the inverting path.
